Female fish changing into dominant colour form

sub dominant females from the group were together. I decided to remove the subdominant females and keep the male and two dominant females only, this arrangement worked out very well in the end, especially in the males favour. The group shared the tank with a large pair of Vieja maculicauda (Black Belt cichlid) another fish that is also found in both Costa Rica and Nicaragua, but not the Great Lake. The tank was a 300g / 1363L, so plenty space form pair forming and spawning. It wasn’t long before pair bonding was witnessed, which meant one female was ignored. Pair bonding consisted of close approximate swimming, body shimmering and occasional jaw locking. Pair bonding in this case seemed to be quite gentle, but this certainly isn’t always the case, Central American cichlids are too intelligent to be that predictable! A vertical stone was chosen and cleaned as the spawning site. I missed the initial depositing of eggs, but I knew straight away they had spawned, as both fish had dramatically changed from a yellow/ green to almost black and white with thick

The fish were only juvenile specimens, so sexing at this stage was nigh on impossible, however, there was a particular dominate fish in the tank which I assumed was most probably a male, this hunch turned out to be correct. Archocentrus centrarchus are herbivorous in nature, but will except most aquarium staple foods with variety like occasional bloodworm. The group grew fairly quickly where sexual dimorphism was becoming a little more apparent. Fortunately, the dominant fish turned out to be the only male in the group, so I was left with 5 females. Two particular females were changing to a slightly darker colour with more pronounced barring and each defending a corner of the tank. The male fish and the other 7
